Could you share a graph dump? From the node ids these nodes were created fairly far apart in time. There are times when we explicitly disable GVN, such as during...

It was already in the graph but with different inputs. Some edges were replaced so that it became equivalent to another node but it requires the canonicalizer to run again...

I've really only seen this on a fairly large machine. It's an Oracle x5-2 with 72 cores running Oracle Linux Server release 6.8. i've also seen problems with running out...

I think this is a problem with the clean build target not cleaning up everything. If I purge my files using `git clean -dxf .` then my build works. Looking...

Graal still doesn't support generational ZGC though I'm actively working on it. I'm hoping to have it in before rampdown but at least until that time JVMCI needs to default...

Sorry I didn't reply sooner. That sounds like a fine interim solution. I agree that automatically selecting something different can be very confusing. Anyway, hopefully this kind of problem will...
